Cookie . . . Who? What happened, yo?

Rocker David is gonna rock The Who - I'm not sure what to say here. What the hell happened in this performance? His vocals were good, with one majorly bum note in the beginning . . . but what happened at the end. Something went very, very wrong. I'm not sure if he got lost, or the band went astray, but that was not what was meant to happen. Also, it was VERY clear on Cookie's face that didn't go the way he wanted it. Did y'all see him cover his eyes and shake his head and grimace? The reason I am pointing these things out is that the judges COMPLETELY IGNORED WHAT HAPPENED! He even looked stunned after the judges spoke. Very interesting evening on the idol . . . maybe it was just different in the studio . . .
